Hundreds of people filmed the south tower before it fell. I haven't seen helicopters in those films. I always wondered why there wasn't an attempt to rescue at least one person with a helicopter on that day! I only watched the towers burn for a few minutes when I was a few blocks away, before I got the hell out of dodge. I didn't notice helicopters then, but that was probably a half hour before the first tower fell.
